Abstract

Described is an economical process for the recovery of factor VIII from blood plasma or cryoprecipitate. In the process, anion exchanger chromatography is conducted using a separating material based on carriers containing hydroxyl groups, the surfaces of which carriers have been coated with covalently boded polymers. The polymers contain repeating units represented by formula (I). ##STR1##
